TEM-wave scattering from a coaxial aline with a material-filled cavity is s
tudied to obtain the reflection and transmission coefficients in a rapidly
convergent series. Their behaviors are studied in terms of medium permittiv
ity, coaxial geometric structure,and frequency. The measurement is performe
d with a water-filled cavity at 1-3 GHz, and is compared with the theory. (
